<h2>Have a common understanding in the classification of organisms</h2>
Explanation:
Taxonomy plays an important role in the classification of organisms to study the organisms on the basis of their properties.
Taxonomy is a branch of biological science that explains the identification, characterization, naming and classification of the organisms thus it is helpful to understand the different types of organisms that are present in the biosphere.
Taxonomy makes the scientist come on one point about the unknown organisms according to morphology, anatomy, physiology and some other properties of the organisms.
Thus a common understanding is generated among scientists of the world.
Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.
The circulatory system works with the respiratory system. The circulatory system transports oxygen through the body, while the respiratory system supplies the body with that oxygen.
